IMPROVEMENT IN LIGHTING ATTACHMENTS FOR ALARM-CLOCKS.

Specification forming part of Letters Patent No. 211,748, dated January28, 1879; application filed November 27, 1878.

To all whom it may concern:

Be it known that I, ALFRED T. KOOPMAN, of Terre Haute, in the county ofVi go and State of Indiana, have invented certain new and usefulImprovements in .Alarm-Olocks; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which they appertain to make and usethe same, reference being had to the accompanying drawin gs, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to alarm-clocks; and it consists in theconstruction and arrange ment of a device attached or connected to analarm-clock for the purpose of igniting one or more matchesautomatically at the same time as the alarm is sounded, for the purposeof kindling a fire in a stove, grate, or other contrivance at any timeof day or night, as will be hereinafter more fully set forth.

In the annexed drawings, to whichzreference is made, Figure 1 is a frontelevation, partly in section. Fig.2 is arear elevation, partlyinsection, with the casing removed. Fig. 3 is a plan view, partly insection; and Fig. 4 is a detail view of my invention.

A represents an ordinary alarm-clock mechanism inclosed in a case, B. ais the arbor on which the alarm-sprin g on the inside of the clockworks, said arbor being extended out through the back of the clock-case,and upon its rear end is secured a pinion, b. This pinion works in atoothed lever, O, pivoted at its lower end, as shown. In winding up thealarm-spring of the clock the pinion b is turned from left to right,thereby moving the toothed lever O to the left, and allowing a spring,(I, to act on a sliding pawl, e, to force the same into theratchet-teeth of the power-wheel D. The spring (I, when the lever turnsto the right, acts with sufiicient force on the sliding pawl to keep thelever in gear with the pinion I). When the lever stands in the oppositedirection, or to the left, a spring, d, produces the same result.

The power-wheel D is mounted upon a shaft, f, and works with a coilspring, E. This wheel is formed on its periphery with ratchetteeth h,and upon its side with a circular row of cogs, z.

friction-wheel n.

The above devices are all inclosed within a suitable casing, Gr,attached to the clock-case B, and a horizontal arm or frame, II, is alsoattached thereto, which arm or frame extends to one side of the clockany desired distance.

In the frame H, in suitable bearings, is placed a shaft, F, which is atits inner end provided with a bevel-pinion, on, that gears with thecircular row of cogs t on the side of the power-wheel D. On the outerend of the shaft F is secured afriction-wheel, n. Immediately beyondthis wheel, in the frame H, is a crossshaft, I, provided with a set nutor screw, .1, on one end, and this shaft has also an eye or staple, p,projecting from it, as shown.

In the extreme end of the frame H is a hole, 00, and also a latch, t,and point 8, said latch and point being pivoted, so as to be set ashereinafter described.

To operate the machine the mainspring of the clock is first to be woundup. The alarm- (lial of the clock is then set by turning from left toright, so that the hour it is desired to have the fire kindled will beunder the hourhand. The alarm-spring is then wound up, which throws thelever (l to the left, and allows the sliding pawl e to engage with theratchet-teeth h of the power-wheel. The wheel D is then turned fromright to left until the spring E is wound tight. A match is then passedthrough the hole or eye 00, head first, and then through the loop orstaple p, lettin g the head of the match rest on one side of the Thestaple p is turned down so as to press the head of the match firmly onthe wheel, and the nut or screw J then tightened. The latch t is thenturned down on the match, that part of the latch which comes in contactwith the match being toothed, so as to hold the same firmly in place.Another match is then impaled on the point 8, and the head of this matchbrought around so as to be directlyover, and a short distance from, thehead of the first match.

The machine is then ready for use, and is to be placed in front of thestove, grate, or other contrivance, so as to bring the projecting end ofthe match on the point 8 in contact with the kindling material.

At whatever time the clock is set the alarm will be sounded, and thepinion I) will move the lever O to the right, thereby withdrawin gFFICE.

the sliding pawl 0 from the power-wheel. This wheel is at once set inmotion by its spring E, thereby giving a rapid rotary motion to theshaft F and wheel a. The matches are thereby exploded, and the kindlingwill be lighted.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is-

1. The power-wheel D, sliding pawl 0, with spring d, and the pivotedtoothed lever (3', in combination with the pinion b and the alarmmechanism of an alarm-clock, substantially as and for the purposesherein set forth.

2. The combination of the power-Wheel D and its spring E, the shaft F,with bevel-gear m and friction-wheel a, and a mechanism connected to thealarm mechanism of an alarmclock, for causing said wheel and shaft torotate at any predetermined time, substantially as and for the purposesherein set forth.

3. The shaft I, with loop 19 and set-screw J, for the purposes setforth.

4. The combination of the frame H, with eye 00, the pivoted toothedlatch t, and pivoted point 8, substantially as and for the purposesherein set forth.

In testimony that I claim the foregoing as Y ALFRED T. iioorMAn.
